Question
The equation of a simple harmonic wave is given by
y = 3 sin
(50t - x)
where x and y are in metres and t is in seconds. The ratio of maximum particle velocity to the wavevelocity is
y = 3 sin
(50t - x)where x and y are in metres and t is in seconds. The ratio of maximum particle velocity to the wavevelocity is
Options
A.
B.2 π
C.
D.3 π
Solution
Vmax = Aω; Vw = 
= Ak; y = 3 sin 
(50t - x)
A = 3; k = π/2
= Ak; y = 3 sin (50t - x)A = 3; k = π/2
